Maintaining Air Filters
Due to the environment the system operates in, the filters will accumulate
dust, causing a degradation in filtration and airflow to the system.
Therefore the filters must be replaced periodically with the frequency
depending on the environment, for instance, in clean laboratory
environment - one time per half year.
The first air filter is mounted on the right fan tray and intended for filtering
the air used for cooling the ATCA blades. The second air filter is located at
lower front of the shelf and intended for filtering the air used for cooling the
AC power supplies.
